Recently, web services have presented a new and evolving model for constructing the distributed system. The meteoric growth of the Web over the last few years proves the efficacy of using simple protocols over the Internet as the basis for a large number of web services and applications. Web service is a modern technology of web, which can be defined as software applications with a programmatic interface based on Internet protocol. Web services became common in the applications of the web by the help of Universal, Description, Discovery and Integration; Web Service Description Language and Simple Object Access Protocol. The architecture of web services refers to a collection of conceptual components in which common sets of standard can be defined among interoperating components. Nevertheless, the existing Web service's architecture is not impervious to some challenges, such as security problems, and the quality of services. Against this backdrop, the present study will provide an overview of these issues. Therefore, it aims to propose web services architecture model to support distributed system in terms of application and issues.

This paper describes a distributed system for monitoring the cameras and controlling the pan tilt zoom, banners and slogans. The system satisfies that users can operator the devices in any computer in the LAN of the express way system, and all video stream can be showed in both a video matrix and any computer in the LAN of the express way system as well. We employ web service and converter between network and serial communication line to implement the anywhere-accessing requirement.

Abstract:This publication is on the automation of persistence, with the example of a Legacy solution, in the form of Enterprise Java Beans. While Java EE and EJB’s are depreciated. They are bridged to the present models of SaaS and serverless computing, through the introduction of two new stateful beans, StreamBean and EventBean, for functional, reactive and Cloud based automated persistence with the ability to implement any design pattern template with the Bean.This paper is on the transition from imperative programming in SQL to a NoSQL based serverless design with automation of the persistence layer in the cloud.

An emerging class of technologies defined as Service-Oriented Architecture (SOA) has been heralded as the answer for inflexible IT architecture and promises to reduce operational barriers of current IT infrastructures. In SOA, loosely coupled Web services are integrated to provide dynamic digital capabilities within and across enterprise boundaries. Little research exists on development processes of information systems using Web services and against certain development metrics. One way to perform such research is to propose a development approach, identify the metrics, and embed the metrics into the technique of service composition to allow system development with desired characteristics. This paper reports an approach to information system development based on Web services composition and the metrics designed for such approaches. This approach is based on semi-automatic, interactive, and iterative Web service composition -- a hybrid technique based on developing and searching an AND/OR graph for composite services discovery while taking into consideration human judgment for solution selection and validation by interactions in an iterative way. The composition process leverages historical Web service usage data and provides helpful suggestions to the users regarding available component services. The authors propose that the metrics can investigate the characteristics of such development approaches.
